Agricultural machines and mechanization

A.Y. 2020/2021
Overall hours
Learning objectives
The student will know the basic aspects of Agricultural Machines starting from the internal combustion engines functioning, to the tractor structure and functions and the basic criteria to optimize the coupling between tractors and machines. Successively, they will know the classification and the technical characteristics of the main agricultural machines as well as the criteria for their selection and rational use.
Expected learning outcomes
Knowledge of the tractor characteristics, its functioning and optimization of machines coupling; knowledge of the technical and operational characteristics concerning the main agricultural machines.
Course syllabus and organization

Single session

Lesson period
Second semester
The teaching program does not change, as well as the reference material. Teaching is delivered remotely in synchronous mode, with the help of the MSTeams platform, following the timetables defined by the Didactic Secretariat. The methods for verifying learning and the related assessment criteria remain unchanged.

GENERAL ISSUES - Soil characteristics; Force, Mechanical Energy, Power, Efficiency; Endothermic engines (Diesel and Otto cicles): characteristics values and parameters of engines; Fuelling, lubrication and cooling systems; Calculation of power and characteristic engine's curves; Transmission ratio and components.
TRACTOR - Power transmission; Propulsive and supporting elements, Grip and resistance to forward movement; Towing hitches and weight bearing hitches; Dynamic engine power balance; Operational selection criteria.
AG-MACHINES 1 - Soil tillage machines; Seedbed preparation machines and seeders; Machines for mineral and organic fertilization; Machines for chemicals distribution; Machinery costs evaluation.
AG-MACHINES 2 - Equipment and machines for grove and vineyard operations; Grain crop harvesting machines; Root or tuber harvesting machines; Haymaking and forage harvesting machines; Vegetable harvesting machines; Fruit harvesting equipment and machines; Machines for harvesting fruit from the ground (olives, hazelnuts, walnuts, chestnuts); Machines for harvesting hanging fruit (olives, fruit for industrial processing).
Prerequisites for admission
Knowledge about agricultural machinery and mechanization are useful for students interested to the course.
Teaching methods
The course lasts 64 hours and follows the timetable established by the Didactic Secretariat for the Degree Course. The total 6 ECTS are composed of 3 ECTS of Frontal Lessons and 3 ECTS of Classroom Exercises. The teaching is provided through the projection of slides.
